Support for (simple) date & time arithmetic

I often find myself needing time calculation, such as the number of hours between midnight and 9:30am. Or the number of days between 25th October 2013 and 25th December 2013.

        Probably like other calculator heads people may have more than one paid/free scientific calculator (I collect programmable vintage working calculators - my pride and joy is an HP-41CX with add-on tape reader) app so if date and time arithmetic not possible how about the ability to put a link in to call another calc app that can?
        It could be done with a free app and permissions granted.

        I use markdown to create workshop and seminar outlines. I need to check my timings. Time/Date arithmetic is the only thing I need. It would solve a huge problem I haven't seen solved anywhere else

        It'd be great to calculate split times, like:

        8:12.5 / 4 => 2:03.125

        Yes! Would love to be able to do: date1 - date2 = days between
